I've been trying to use interactionCreate event, but somehow it's not working. I'm not sure why, and I didn't find exact documentation about this event, only that it's used for executing slash commands. However for this purpose I use messageCreate event, and it's working fine.

const Event = require('../handlers/Event.js');



module.exports = new Event('messageCreate', (client, message) => {

    if (!message.content.startsWith(client.prefix) || message.author.bot) return;



    const args = message.content.substring(client.prefix.length).split(/ +/);

    try {

        const command = client.commands.find(cmd => cmd.name == args[0] || cmd.alias == args[0]);

        command.run(message, args, client);

    } catch (error) {

        message.channel.send('Wrong command.');

    }

});

What's wrong with my interactionCreate event?

const Event = require('../handlers/Event.js');



module.exports = new Event('interactionCreate', async (interaction) => {

    if (!interaction.isCommand()) return;



    if (interaction.commandName === 'join') {

        await interaction.reply('join');

    }



});
